3cm dilated/50% effaced... when is the day??

Karishma

I had my vaginal check up today and the doctor said baby is extremely low, I'm 3cm dilated and 50% effaced. She also said that I might see her at the hospital in a day or two. But my question is, where are the contractions? I'm not feeling any pain.... no sign of water leaking either. When will I go in labor?? This is my second baby...
